@a2l007 @jihoonson This is the problem I worry about. Number of task slot is fixed at configuration level. Currently, there's no way to enlarge the number of task slots without rebooting middle managers to take the new number in effect, which means tuning the number is not easy in production. And In order not to block the index tasks, a complicated algorithm is needed. I think threading model is a simple enough way but without violating any current design principles. Task slots provides a way to parallelize the task between middle managers, threading model provides a way to parallel the task inside a task. They're not conflict. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
